Study of the Typological Characteristis of ISS Crew Operators Activity at the Stages of Long Term Space Flight (Tipologia (Typology)) - 02.25.15

Science Objectives for EveryoneIdentification of objective features of typological manifestations of operator activity, which can be used for assessment of the actual mental state, prediction and correction of quality of professional task performance in a space flight.

Science Results for Everyone
Space flight is a head rush. On the ground, crew members exhibit a high level of professional skill, able to perform logical and spatial tasks and to develop adaptive biological control skills. In space, however, microgravity causes a rush of blood to the head, and this investigation found that all subjects begin to struggle with difficult activities and problems, especially ones requiring logic. Researchers sought to identify objective factors that could be used to predict and correct the quality of performance in space. Regardless of performance during flight, most subjects were able to successfully solve problems once back on the ground.

Description
Assessment of preservation of individual typological features of operator activity and their predicted value. Assessment of preservation of adaptive biological control skill (ABC) and the correction effect.

Generation of objective data on preservation of the adaptive control skill in the actual flight with a rush of blood to the head that is natural in weightlessness will allow to develop methods to improve the cosmonaut readiness for various types of operator activity when stochastic and determined stimula act.

Complex NEIROLAB-2000I provides taking readings, amplification and processing of the following physiological functions and factors: electroencephalogram; color selection procedure and verbal characteristics when performing Lscher psychological test; efficiency factors of playing computer games (the following is measured: number of correct answers, errors, time of task implementation, etc.). All the data generated during the experiment is recorded on a hard disk of onboard computer Laptop Think Pad A31P RSK1 and at the end of the Expedition the data is recorded on memory card PCMCIA and removable disk HDD-FOTO-SM which upon the Expedition completion are returned to the ground.
